WebIon implantation is an effective way of introducing a single impurity into the subsurface region of a material to a depth of several microns. The degree of II-related modification of the target depends on its properties and II parameters, such as the type of implanted ion, ion energy, ion beam current density, target temperature, and so on. Web16 jul. 1996 · Implantation of semiconductor devices at very high beam currents can often lead to device damage due to charging. Depending upon the implant conditions, type of charge control system used...
